Cybersecurity experts have uncovered a new malware attack that clones legitimate browser extensions to steal user credentials. This sophisticated technique involves creating a perfect replica of the extensions’ icons, HTML popups, and workflows, while temporarily disabling the legitimate extension. Threat actors can infiltrate systems by disguising the malicious extension as a harmless utility in browser extension marketplaces such as the Chrome Web Store. The malware operates covertly, activating its malicious functions only when it detects the presence of specific web resources associated with target extensions. Once activated, the malware replaces its icon with the target's icon and uses the "chrome.management" API to disable the real extension, misleading the user into interacting with the fake. This type of attack can lead to hijacking of online accounts and unauthorized access to sensitive personal and financial data. The method exploits user trust in visual cues on their browser interface, underscoring the need for heightened alertness to potential browser extension frauds.
